The **LEDPRO20WH** is a high-performance, 20-watt architectural LED floodlight, typically part of the Luceco (or similar industrial brands) product line. It is designed for durability and high luminous efficacy. Below is a breakdown of its primary electronic components and specifications. --- ### 1. Key Electronic Specifications The performance of the LEDPRO20WH is driven by its internal circuitry, which converts AC mains power into regulated DC power for the LEDs. | Component / Feature | Specification | | :--- | :--- | | **Input Voltage** | 220-240V AC (50/60Hz) | | **Wattage** | 20 Watts | | **Luminous Flux** | Approx. 1,600 - 1,800 Lumens | | **Color Temperature** | 5000K (Cool White) | | **Driver Type** | Integrated Constant Current Driver | | **IP Rating** | IP65 (Dust tight and water jet protection) | --- ### 2. Internal Electronic Parts The device consists of three main electronic subsystems: #### A. The LED Array (COB or SMD) Modern LEDPRO units typically use **SMD (Surface Mounted Device)** chips mounted on a Metal Core Printed Circuit Board (MCPCB). * **Thermal Management:** The MCPCB pulls heat away from the LED junctions and transfers it to the aluminum housing, preventing "thermal runaway." * **Efficiency:** Designed to provide roughly 80-90 lumens per watt. #### B. The LED Driver (Power Supply) The driver is the "brain" of the unit. It performs the following functions: * **Rectification:** Converts AC input to DC. * **Voltage Regulation:** Steps down the voltage to the level required by the LED string. * **Surge Protection:** Includes MOV (Metal Oxide Varistor) components to protect the LEDs from voltage spikes on the grid. #### C. PIR Sensor (Optional Accessory) Many LEDPRO models feature a "plug-and-play" electronic interface for a PIR (Passive Infrared) sensor. * **Interface:** A specialized socket (often behind a circular cap) allows for a sensor to override the internal switch. * **Control:** Includes potentiometers to adjust *Lux* (light sensitivity) and *Time* (duration of light). --- ### 3. Wiring Configuration For installation, the electronic connections are standardized as follows: ```json { "Brown": "Live (L)", "Blue": "Neutral (N)", "Green/Yellow": "Earth (E) - Required for safety" } ``` --- ### 4. Safety and Protection Features * **Thermal Cut-off:** The driver circuit often includes a thermal fuse that cuts power if the internal temperature exceeds safe operating limits. * **Diffuser:** While physical, the prismatic glass or polycarbonate diffuser is optically engineered to minimize glare from the high-intensity LED chips.
